/ This invention pertains to finishing welts, that' is to say, to that type of trimming strip which is extensively used to cover the meeting edges of upholstery fabric of furniture, and to trim the edges of covering materials in automobile bodies Y ployed for a Wide variety of uses, and includes I l5 such relatively soft or loosely constructed material as is used by dressmakers or milliners, as well as hard dense moulding useful in the structural l arts, furniture making, or by automobile builders.

In accordance with one known prior procedure, such trimming has been made by braiding twisted stranlsof paper, and while trimming so made is ideal for certain purposes, it has little resiliency; usually necessitates the employment of a cementitious binder to hold its parts in proper relation; and it doesnot possess a pleasing texture or surface appearance such as to make it desirable in places where it must lbe exposed to view.

I have now discovered that by using regenerated `cellulosic material in thinsheet form (for example, the material known to thetrade as Cellophane") either in making the stuier of the strip trimming or the jacket thereof, or both, or to form a substantial portion of, the stuffer and/or jacket material, greatly improvedresults are attained.

` For example, if the stufler consist of one or more strands of Cellophane, either plain or creped, so gathered together, for example by passing the material through a trumpet guide as to form longitudinally extending folds or laminations, such stufer is far more resilient than but without necessarily causing the Cellophane to lose its inherent resilient characteristics. By

strands as herein employed, I intend to include untwlsted ribbons of sheet material (for example cellophane which mayreadily-be slit into narrow strips of the order of 3*," width) as well as widel ribbons,folded sheets, twisted or spun single sheets, spun and/or twisted aggregates of ilbers, or twisted or braided multiples of elementary strands, and whether the strands befof one material, or of a combination of materials, for example,- wire or paper covered with Cellophane or other substance. If strands having the charl acteristics of Cellophane be mployed in maklng, as for example, by'braidi g, a jacket and/or the stuiler, or combined with strands of other 'I materials in making either of them, and/or 'if the assembled stuffer and jacket be subjected to heavy moulding pressure, the resulting tr will retain indeiinitely the cross section i parted during assembly of the parts or imposed by moulding pressure, without recourse to the employment of an impregnant binder. Thus an acceptable strip trimming maybe made without using a binder if desired, thereby reducing the cost of preparation and in particular reducing weight, so that the resulting trim becomes acceptable for certain purposes fromv which the lpaper trim is excluded. Moreover, this material provides a trim or a stuilg'er having a very smooth glossy surface which greatly facilitates the insertion of the trim into an outer casing or tubulature,-while by reason of the pleasing appearance which may be given to this new trim, as for example by employing stuffer or jackethforming strands of contrasting color, it is possible to produce a trim having, a surface iinish such thatit may be exposed to view without enclosure or without further treatment. Since regenerated cellulose is substantially transparent and ,may be obtained in many colors, it is possible to 'design a trim having very artistic and pleasing color effects, particularly as the stuifer may be ex posed to view if desired, by making the outer jacket of a very loose and opentexture. Obviously combinations of regenerated cellulosewith other materials, for example, cotton, silk, wooi, linen, paper, metal wlrefor lthe like, may be desirable for certain purposes. For certain effects, for example, I make the stutter, at least in greater part, of regenerated cellulose by reason of the high resiliencyl of the latter under normal conditions, and the artistic effects obtainable from its use. 4 Y

More specically, among the advantageous combinations which may be made, within the purview of the invention is a tubular trim devoid of a core or stuier) in which ail of the strands are 'of regenerated cellulose or which a part of the strands are olf-regenerated cellulose and a part of the strands are of a textile sub-v stance or consist of metal wire or other materials;-orin which some or all of the strands are of regenerated cellulose enclosing a core of other material, .for example, a textile substance or a metal wire.-

' It-is also within thepurview of the invention to provide a trim comprising a tubular jacketl enveloping a stuier or core, in which the, jacket comprises strands -of` the kind or kinds, and as sembled inany of the ways justA above referred to, or alternatively, wherein the jacket consists wholly of strands of a textile'material or wholly of metallic wire or of any desired combinations thereof, or of any such materials associated with strands of regenerated cellulose, andv in 'which the stuier may consist wholly oi regenerated cellulose, Whether in the form of one or more elongate strands or strips of crumpled or folded multi-ply, or of rolled sheet material, or of one or more twisted or spun strands of lsimilar material, and whether each individual strand is or Y Asome of them are provided with a core of a textile substance or metallic wire.

Further, the stuier may comprise elongate strands or'strips'of regenerated cellulose in am! of the forms just mentioned, associate-:i with sim-y ilar or diil'er'ently formed strands of a textile substance or substances and/or with' inclusions of metallic wire; or such a strand or strands of regenerated cellulose associated with one ormore strands of metallic wire alon'e. For particular purposes the stuffer may comprise or consist of one or more elongatel strands of textile material either insheet form crumpled, folded,.rolled, or multi-ply, or of sp'un or -twistedstrands with or lwithout cores of metallic wire or cores of regenerated cellulose or with associated metallic wires.

In thus referring to textile substances I intend to include thereby such materials as cotton, silk, linen: wool; jute; hemp, sisal, paper, asbestos, or in fact any material capable of being spun, twisted, extruded, or otherwise brought into the form of an elongate, ilexible strand, 'and whether such strand consists merely of a single Ase 'material may be shaped approximately to the desired final cross-section prior to orwhileformaggregate of the primary ,libera or consists, oi

fabric previously made from the primary fibers by usual 'textile processes.

The tubular trim or the .jacket for the comprising the inner stuiieror core may be of close texture'substantially devoid of visible openings or interstices or, on the other hand, the tubular trim or jacket may be of open texture oi any degree of loosenessdesired. The stuifer ing the jacketror the nal cross section of the' composite trim may be imposed while forming the jacket, or in part or wholly by subsequent lmoulding operatic-n; the material may bey impregnated, coated, colored, or otherwise subjected to any appropriate medium, reagent, or physicaltreatment either before, during, or after the asso--v ciationof the stuil'er and jacket, or at any of such stages .in the operation; the trim ymay be While;

of illustration to braiding as one desirable mode of associating or'assembli'ng the jacket forming strands, I wish to emphasize the fact that these strands may be associated in other ways, as by weaving, knitting, winding, etc., and when herein I refer to associating the jacket forming strands, I expressly use this term as broadly inclusive of any appropriate method of bringing the several strands vinto such assembledrelationship as toV form a jacket structure comprising individual strands vso v concatenated, interlooked, interlaced, interlooped, intercrossed, or otherwise correlated Aas to form a flexibie, mouldable and coherent structure.

Referring to the drawings, the numeral I designates a length of my improved strip trimming, such trimming comprising the stuffer cord l and a jacket comprising the interbraided strands 2. The stuifer la preferably consists, in whole or in major part at least, of one or more sheets of a thin cellulosic derivative, for example, a regenerated cellulose such as is known under the trade name Cellophane, This material 'may be secured in sheets of desired width and substantially unlimited length and in such thicknesses and colors as may'be desired. It is very tough and strong, substantially transparent, and when crinkled, doubled or folded upon itself, it exhibits a marked'tendency to spring apart, due to its inherent resiliency, and thus more or less to resume its original position. Thus when such a sheet is condensed as by folding orcrinkling, into small dimensions, it exerts a substantial pressure against any surrounding enclosing walls. v

The strands 2 which form the jacket are also preferably made of cellulosic material of the type above referred to, although for some purposes I may prefer to employ other substances, in part or in whole, in making the jacket, for example cylindrical, ribbon-like, or other strands of paper, cotton fiber, linen,.hemp, silk, artificial silk, wool or, in fact, any other animal or vegetable substance capable of being worked into strands of uniform character, transverse dimensions, and tensile elongation, .or I may for some particular purposes use fine metallic wires in substitutionA sirable characteristics which are not readily attained by the use of jackets of other type; for

the stuier may be made by weaving; or by a knitting operation, using one or more strands to form the courses of knitted loops; or that the jacket may be made by spirally wrapping a strand or strands -about the stuffer. If spirally wrapped strands be employed,` I preferably arrange sets of strands in helices of opposite hand to form a balanced structure.

The strip trim of the type illustrated in Figs. 1 and 2 may have any appropriate and desirable cross-sectional shape and contour, for example, round, as illustrated in Fig. 2. Iny Fig. 9 a semicircular construction is illustrated at Ib; a semicircular section with a depression or tack groove in its curved face is shown at Ic; a substantially triangular section is illustrated at Id; a substantially square section is shown at le; and an elongate rectangular section is illustrated at If. It is to be understood that the sections illustrated are merely by way of example and that substantially any cross-sectional shape desired may be imposed upon the trim, either during the assembly of the stuier and jacket or subsequent thereto. For example, the desired cross-sectional shape maybe approximated by passing the stuffer through a braiding machine die having an opening approximating the desired shape of the trimming,-it being possible by a braiding operation and by the use ofsuch a shaped die opening to cause the braid to assume a cross-sectional contour substantially like that of the opening. However, after the braiding oper-ation has been completed, the final shape desired may be imposed by passing the material through appropriate dies, heated if desired, and with the assistance, if necessary, of some suitable impregnant, coating, and/or binding material.

By reason of the resiliency of the folded stuffer material, it tends'to spring apart and forml a porous filler for the braided jacket, and thus by the use of such stuffer material in comparativelyl 4small quantity, it is possible to make a strip trimming of large diameter but comparatively light in weight. Moreover, the interstices of the stuffer as thus formed provide ready means wherebythe stuier may, if desired, take up a large proportion of a fluid filler, binder or plasticizer as illustrated at lx in Fig. 2*, if for any reason such material be desired to impart its particular characteristics or properties to the completed trim.

In braiding the jacket from the strands 2,-- highly ornamental effects may be produced by selecting strands of different colors, and in this way the jacket in its finished condition may show spots, lines or figures of artistic appearance which, together ywith the naturally glossy surface of the strand material renders the iinished trim desirable for use in exposed positions. While the closely braided jacket shown inFig.

1 is desirable in many instances, particularly.

where a firm, moulding-like trim is desired, I prefer in some instances to make the jacket'of more open construction. Thus as shown in Fig. .3, the trimming strip 3 comprises the stuil'er 4 which may be of the same material as above described and having the same characteristic of hllgh retion in which the trimming strip 'l comprises the stuffer 8 enclosed in an envelope 9 (for example,

. cheapness are requisite, asythe stuifer 8 may be I to sillency,-while the jacket comprisesstrands 5 interbraided or otherwise assembled to provide ,anopen-work texture, leaving large meshes or openings ythrough which the stuier material is exposed.l `Since' thestufler is placed under compression, either before or during the braiding op-l eration, the material of the stuifer tends to bulge out, as shown at 6, through the openings in the netlike jacket, thus providing a surface configuration of ornamental appearance 4which may be enhanced by the use of contrasting colors in the s tuier andin the jacket-.forming strands. Such a trimming strip may be made of very considerf able bulk for a given weight material, and though much softer than that having the closely braided jacket, nds utility both as an ernamental trim by itself, and also as a hller for tubulatures such as are used in certain furniture and other trim. .1 f

In Fig. 5 I have illustrated a further rnoclilic'a a single sheet of 'thin material' wrappedabout the stuer) which in turnl is enclosed in an outer jacket comprisingthe assembled strands I0. The enveloping sheet 9 may be. of Cellophane or like material, preferably transparent,

or of acharacter selected particularly lfor its 0 waterproof` or moisture-resistant qualities, while 3 ample, A`this stuifer may be of a.A very soft, porous' or bibulous material capable of absorbing large quantities of a fluid reageit, adhesive, orilller, or which may be left in a dry fluy condition and protected 'from moisture by the enveloping sheet 9. Trimming of the kind shown in Fig. 5 may be desired where'exibility, large bulk, and extreme made of some extremely cheap material such as cotton linters, creped wadding, batting or the like, the latter being so encased in the wrapper 9 that its color or other characteristics are hidden from view.

- In Fig. 7 I have illustrated a'modiiled 'construction,.useful under some conditions, inwhich the braided to form a close, firm, tubular structure in whichrthe braided strands bear against each other. .so as substantially to' prevent collapse of the tube under radial compression. Preferably. 6E the strip thus formed by the braiding operation is then Apassed .through some reagent material which cruises the constituent strands lz to unite integrally with. one' another, as indicated at Il in Fig. 8. Forexample, if the strands l2 be of Q.anitro-cellulosic derivative, they may thm be integrated by passing the tubular braided material through a bath of'acetone or similar solvent, the material being allowed to remain in the bath just'long enough to .cause the surfaces of I6 the strands tobecome adhesive. -Su'ch a trim, if madefrom strands of .contrasting colors, is very bmamentaLstrong, light in weightandr pable of many usesin which the strands with the en closed stuffer are not so d f 7 0 In preparing trim such as shown in Figs'. 1 to 5,

lfor example, I preferably employ a laminated' i.-st uf!er, as illustrated at Il in Fig. 10Q' In vthus .:rferring vstutter as laminated, I doA not intend 'to'iridicatethatit isnecessarily made up 7"; oi' a'pluraii'ty of independent'layers. or that such stuifer element is omitted entirely. lin this trimming strip il, the jacket strands .I2 are interlayers are of uniform dimensions, but rather to indicate that the stutter comprises overlapping folds or plies of the material employed, whether such plies be all integral or not, or whether they` consist of sheet material or `are such things as rovings or the like arranged in bundles.

As illustrated vin Fig. 11, I prefer to proceed Aby taking a sheet or strip I58L of the selected material, such as Cellophane, of proper thicknessand color, and by gatheringthis sheet 4together, for example by passing it through a trumpet guide, causing it to assume more or less the desired cross-sectional contour for delivery to thebraiding machine. As shown at i5 in Figs.

' l1 and 12, this sheet has been reduced to a cord Instead of using a single-ply sheet, as indi- .cated at I5", I may, as shown in Fig. l5, employ sheet vmaterial i9 itself made up of a plurality of like or unlike plies or layers 20. For example, for some purposes, as for instance in making the trim of Fig. 5, the sheet material i9 may be a lamellar bat'of sheeted fibrous aterial, such .as cotton,'ootton linters, kapoc, silk oss, wool,

wood-pulp, creped wadding, ,alpha cellulose, or

in fact any other desirablev material, and .this lamellar material I9 may comprise layers of dif- Qferent kinds, for example cellophane and alpha cellulose, in alternation or other appropriate order. This material may .in the same way as the material I5a be gathered together to form a strand-like element 2i of selectedcross section. In making the relatively thin or vfine strands which are used in forming the jacket, I prefer to take a ribbon I5 (Figi 17) of the-desired material, for example Cellophane" or the like, and to twist it on itself, either dry or aftertreatment with asurface solvent or adhesive, to form a strand I1 which maybe more. lor less circular in section,-although a Asingle. ribbon of such resilient sheet material tends, during the twisting or spinning operation, to assume a somewhat ir-v regular section. This tendency, howevenmay, if

desired, be avoided by employing. a plurality of For some purposes strands which 'are not of true circular cross section at all .points are to be preferred, for the reason that the irregular, strands reflect light from 'their various facets, thus en- Y handing the ornamental character of the nal In twisting the-ribbons i6 to .form the strands Il, sumeient twist 'is preferably exerted -toex- -ceed the limit of elasticity of the material or the st randsare held twisted and under such' condi tions that they acquire a-permanent set so thatthev completed strands show littletendency to untwist. While'I prefer to .use strands such as:

il, I may, ifA desired,;'. employ spun orl twisted strands i8 comprising constituent fibersA I9 .or ysn of any suitable textile. material, including "cotton, linen, lsilk, hempfdute, paper, and the icellulose derivatives or, in fact, evenmetallic wires. yand` such strands I8 may be single-ply yarns, or braided-or twisted multi-ply yarns; as

desired. As another possibility, these jacket- `forming strands may have cores of twisted paper' textile or other material, or alternatively the core covering may be enamel or the like.

In Fig. 19 I have illustrated a useful procedure in making strip trimming such 1as shown in Fig. 1. Thus from a, roll 22 of the sheet material i5 I draw the sheet off and if. desired coat it with an appropriate binder, surface-solvent, cement, plasticizer, coloring material, filler, or the like, in liquid, plastic, or powdered form, de-

livered for example from a reservoir 22* and guide 23 where it is gathered into the strand I5.

This strand is then passed through the die of the braiding machine 24, the die having4 an opening of any, desired shape, either circular, or 4noncircular, and in passing through the braiding machine a jacket comprisingr strands l1 is ap plied to the. stuffer strand I5. ,The stuifer with its enclosing jacket may then be passed between suitable moulding or die rolls 25 and 26 whichimpose upon the material the nal desired crosssectional contour. This contour may approxi--v mate that imposed by the braiding die or may be quite different, if desired, the braided jacket imposing little restraint to prevent proper moulding when suitable pressure is employed. After passing through the dies 25 and 26, the material may be coiled up to form the roll 21, or delivered to any other mechanism or process for further treatment. y

In Fig. 20 I illustrate the steps of forming they trimming shown in Fig. 5. Thus a roll 21 of material such as shown at I9, for example, is passed through the trumpet guide 29, while material such as that shown at l5 is delivered from a roll 30 to an exterior trumpet guide 3|. This latter guide causes the material i5El to wrap about or envelop the strand 8 formed from the material i9, and this composite. stuier, including its `outer envelope of the material i5, is then delivered to the braiding machine 24' where it receives the outer jacket formed of the strands I0. The vmaterial may, if desired, be passed through a receptacle 32 containing a bath of any desired reagent, for example, one 'which will cause the edges of the envelope material to become integrally or adhesively united. Ihe ma-V terial now` passes between the die rolls 25l and 26 where it receives its nal shape and then passes to the roll 21B where it is wound up.

In Fig. 21 I have shown steps in the process of making the material illustrated in Fig. 7. In

this instance the braiding machine 24h associates the strands l1 to form the tubular struc- Y the tube to form a flat ribbon, after which it may Vbe coiled or shown at 2lb. f V

` For certain purposes where the strip trimming is to be exposed, I prefer to provide it withappropriate openings for the reception of fastener ele,

ments. Thus, as illustrated in Fig. 9l, the substantially semi-circular trim 34 is furnished with the openings 35 adapted to receive screws or tacks whereby the trim may be attached directly to a supporting surface. APreferably these holes are furnished with countersunk ends 36 so that the heads of. the attaching screws or tacks may be broughtflush with the surface of the moulding. -Y

In Fig. 22 I have shown in section a trimming strip comprising a stuifer 31 of lamellar sheet `material and in association therewith a plurality of metallic wires 31 shown as disposed in the angles of the strip where they assist in preserving the shape imposed upon the strip during the process of manufacture. The stuifer is shown as having an outer coating 38 of appropriate material, for example, a water-repellent lm of rubber latex, and this stuifer is enclosed 'in a jacketomprising associated strands 39 and 40, the latter having metallic core wires.

In Fig. 23 the lamellar stuier comprises a plurality of thick, soft rovings 4I disposed in a bundle with interposed coating fllms 42 of. rubber latex or other appropriate binder (preferably of water-repellent character). This stuffer is enclosed in a jacket of associated strands 43, preferably twisted or braided from cellophane or equivalent resilient material.

In Fig. 24 the lamellar stuier comprises a bundle of rovings 44 enclosed in a multiple wrapping 45 of resilient Cellopha'ne or other l balanced character, thereby to avoid tendency of.v

the trimming to twist or curl.

In Fig. 26 the jacket is shown as consisting of sets 4B and 49 respectively, of interwoven warp and weft strands, while in Fig. 27 the jacket is illustrated as consisting of strands 50 and 5i interknitted to form successive courses of a knitted jacket.

Fig. 28 shows a trim, like that of Fig. 3, for example, after it has been moulded to non-circular shape, and comprising the stuffer l* encased in the open mesh jacket comprising the strands 5, and a coating or impregnating material `52 exposed between the strands of the jacket and covering the outer surface of the stuffer.

In Fig. 29 I have illustrated the utility of my improved strip material on a core or ller for a tubulature I,t which may be of metal,\gubber, paper, textile fabric, or any other material or compound.

In Figs. 30 to 44 inclusive, I have diagrammatically illustrated further combinations of re generated cellulose, textile material, and wire, indicating the kind of materialby vappropriate legends.I The structural arrangements are obvious from inspection.
